Mophie Powerstation XXL Review

The Mophie Powerstation XXL is a powerful, 20,000mAh power bank that has a lot to offer. It comes in a fabric case, which feels nicer than the plethora of plastic power banks on the market. Mophie is owned by Zagg Brands, a tech company with several subsidiaries. They produce dozens of different power banks, with a wide variety of capabilities. But the Powerstation XXL is their flagship product.

Capacity & Charging speed

The Powerstation XXL uses a Type C charging cable. When connected to a high-voltage port, it will fully charge overnight from completely dead. The power bank had Power Delivery so it charges within 5 hours.

All in all, the Powerstation XXL can charge up to 3 devices simultaneously, from 3 different ports. It’s compatible with any device that can run on USB power. This includes almost any smartphone or tablet, along with most new laptops and Macbooks. Each USB port provides 18W of output, enough to keep using your tablet or laptop even while it’s charging.

Look and feel

The Powerstation XXL has premium look, with a fabric finish. It’s available in multiple colors, which will match a variety of accessories, decors, and fashion choices.

On the long edge of the XXL, you’ll find a row of 4 LED indicators that display the current battery level. By default, they’re not illuminated. However, there’s a small button you can press to display your level of charge. On the short edge, you’ll find 2 USB Type-A ports, and 1 USB Type-C port which are used for charging all your devices. The Type-C port is also used for charging the Powerstation.

Durability & Construction

The quality of the Powerstation XXL’s build is better, at first glance than your average battery pack. It’s not rated for shock or water-resistance, which is a bit of a disappointment. That said, it’s tough enough to stand up to normal, everyday use. And it’s well-constructed, so you don’t need to worry about short-circuits or overheating.

The battery itself is manufacturer-rated for 500 total charge cycles. What this means is that, under normal conditions, the Powerstation XXL will retain 75 percent of its original battery life after 500 charge/discharge cycles. This is right in the sweet spot for lithium polymer batteries and is good enough for years of daily use. If you end up having any early issues, Mophie has got you covered. They offer a 2-year warranty on the Powerstation XXL.


The Powerstation XXL is 6.26 inches long, 3.05 inches wide, and 0.91 inches thick. That’s about the same size as an iPhone, albeit a little bit thicker. It weighs just 15.3 ounces, which makes it comfortable to carry in a backpack or even a pocket.

For air travel, the Powerstation XXL is perfectly legal. It delivers 3.7 Volts of power, with a capacity of 20,000mAh. This works out to exactly 74 watt-hours, which is the TSA threshold for airworthy battery packs.



Large charging capacity

Approved for air travel

Attractive fabric case

Can charge 3 devices at once



Not waterproof or shock-proof

Only 18W PD output

Final Thoughts

If you’re looking for an exceptionally powerful power bank, the Powerstation XXL offers a lot of bang for your buck. With an impressive, 20,000mAh battery, it provides enough juice for 100 hours of iPhone use. Even on a laptop, you’ll get at least two full charges from your Powerstation.

For more modest needs, you might prefer a smaller power bank. But the Powerstation XXL is relatively compact for its capacity. For most people, it’s an excellent choice.
